Journal ArticleDOI
A Differential Geometric Approach to the Geometric Mean of Symmetric Positive-Definite Matrices
TL;DR: This paper introduces metric-based means for the space of positive-definite matrices and discusses some invariance properties of the Riemannian mean, and uses differential geometric tools to give a characterization of this mean.
Journal ArticleDOI
Conformational analysis of nucleic acids revisited: Curves+
TL;DR: Curves+ is described, a new nucleic acid conformational analysis program which is applicable to a wide range of nucleic Acid structures, including those with up to four strands and with either canonical or modified bases and backbones, and which provides a full analysis of groove widths and depths.
Journal ArticleDOI
Means and Averaging in the Group of Rotations
TL;DR: This paper gives precise definitions of different, properly invariant notions of mean or average rotation and shows that the Riemannian mean rotation shares many common features with the geometricmean of positive numbers and the geometric mean of positive Hermitian operators.
Journal ArticleDOI
A rigorous framework for diffusion tensor calculus
TL;DR: The space of positive definite tensors is used to construct a framework for diffusion tensor analysis and a new measure of anisotropy, and a method for tensor interpolation are derived.
Journal ArticleDOI
The Closest Elastic Tensor of Arbitrary Symmetry to an Elasticity Tensor of Lower Symmetry
Maher Moakher,Andrew N. Norris +1 more
TL;DR: In this article, the closest tensors of higher symmetry classes are derived in explicit form for a given elasticity tensor of arbitrary symmetry, where the mathematical problem is to minimize the elastic length or distance between the given tensor and the closest elasticity Tensor of the specified symmetry.
